What type of ions are electrons colliding with to cause resistance in a circuit?
a. metalloids
b. metallic
c. gases
d. non-metallic

Metallic ions are electrons colliding which cause resistance in a circuit.

Explanation:  

At the point when an electric flow through a conductor, for example, a metal wire, the moving electrons can slam into the particles in the metal. This makes it progressively hard for the current to stream and causes resistance. There are a few factors that influence the resistance of a conductor; material for example copper has lower opposition than steel. Metallic particles have more prominent opposition. Thickness of the metallic wires have more prominent resistance. Therefore, utilizing metallic will cause resistance in a circuit.
